I assume you modelled the entire thing? Looks like the real model, only the lower front section looks a little bit to flat (if I remember correctly its more rounded?).I'm just getting into 3D modelling with Blender (I have 5 years of experience with parametric 3D modellers) so I'm no expert there, however I would suggest:- The red parts looks like they are metal. If you paint metal, its no longer "metal" for the renderer and therefore you shouldn't use a metallic shader. For my taste its way to shiny (= not rough enough).- Also both texture (red and metal) are to "clean". You should use surface imperfections, etc.- It's a space ship, where ist the space background? -> Space HDR with stars- A planet in the background is also always nice looking
